2. Install an SDK (Optional, Recommended)

While you can interact with our REST API directly, our SDKs for popular languages like Python, Node.js, Java, and PHP simplify integration. Install your preferred SDK via its package manager.

pip install xelfprocessing-python

3. Make Your First API Call

Use your API keys and an SDK (or a direct HTTP request) to make a test call, like retrieving a list of available payment methods or creating a test payment.

import xelf
xelf.api_key = "YOUR_SECRET_KEY"

try:
  recovery_status = xelf.Decline.submit(decline_data)
  print(payment_methods)
except xelf.error.XelfError as e:
  print(f"Error: {e.message}")
